5 citizen of the United States, have invented certain new and useful-Improvements in Car Wall Structures, of which the following is' a full, clear, and exact description, such as will enable others skilled in the art to which '10 it appertains to make and to use the same,

reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited 1 5 tothe exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occurA to persons skilled in the art.

20 f' My inventionl has for its object to provide an all metal car construction of novel character which is unusually strong for its l, weight and durable throughout, which may be conveniently and economically manufac- 25 tured and transported, isweather proof and which possesses certain other desirable and advantageous features to be hereinafter described and claimed. My sheet metal wall structure vis .applicable to box, automobile, gondola, stock or any other type of railway equipment.

rllhe ends of railway cars are subject to considerable stress due tothe shifting of the A lading. These blows' are imparted to the end over the entire area thereof, or to local or concentrated thrust. Wheat is loaded to substantiallyvthe top of the car which causes all the blow |to be imparted over' the entire area of the' end. Lumber is loaded to thet top and upon impact -thetop boards shift causin a blow to be imparted at the top of the'en vSand, chats and other plastic loads and light ipe cause blows at the middle of the car, w creas rail, steelplates', castings and the like cause blows at the bottom of the Fig. 11.

Car.. s

While, of course, efforts are made block the lading in the car, the heavy locomotives, the emergency air brake andthe classifica! tion hump break"th`e lading away from its moorings and throw it 'againstthe end of the car.

. rigid end toa car, and particularly a. large box car, materially strengthens the enform of the alight wellgas strong.. As freight cars are frequently damaged in wrecks and by other unfair usage, any end will be damaged in service, therefore,` it must be capable of being easily-repaired with such meagrel facilities as the railroads are equipped with at their outlying repairpoints. In the drawings: Fig. l shows an end elevation of a box car with my endy applied thereon.

F FigL 2 shows a section on line 2-2 of 1g.

Fig. 'shows an elevation of one of the plates before it is applied to the car.

Fig. A: shows a vertical cross section on line 4 4 of Fig. 3. Y

Figs. 5 and 6 show modified sections on line 4-4 of Fig. 3.

Fig. 7 shows Van elevation of a modified plate before it is applied to the car.

Fig. 9 shows a vertical section of two metal plates secured together formingfthe end of a box car, said section taken along the center line of-the car showing a modifed form. a

Fig. 10 is similar to Fig. 9 andvshows another modification.

Fig. 11 is an elevation of the metal plate before it is applied to the carL wherein the horizontal portions above the panels are wider thanthe. horizontal portions below the anel.

Flg. 12'is 'a section on the line 12-12 of Numeral l is the side wall of the car, 2 the under frame, 3 the roof to which my plate metal wall -structure is attached by various and any convenient means. Numerals 4, 5 and are Dtop, middle and bottom sheets respectively of a car end .wall made in three pieces.` However, the end may be made in a'single sheet or anyv num- Fig?. 8 is a section on the ,line 8 8 of 1 :side walls of a rectangularv panel pressed from the elevated portion of the last mentioned panel. Margins 10, 11 and 12 are then formed between panel within panel.

While I have shown in Fig. 3 three panels within panels, rectangular or otherwise, my invention covers any plurality of panels within panels depending upon conditions to be met by the designer.

In order to conserve horizontal space it may be advisable to reverse the direction of some of the panels without diminishing the strength of the panel an as entirety. Suggestions along this line are shown in Figs.

i Il" 5 and 6. Panels of diiferent depths are thus obtained. The deeper panels, such as shown in Figs. 6 and 8, have greater strength than the shallower panels when acting as beams. Fig. 2 shows the end wall comprising three duplicate plates and further shows nailing strips y16 secured to the sheet by bolts 17 to whic the lining boards are nailed. 'Ilhe end li 'ng 18 is to prevent moisture due to condensation coming in contact with the lading and'also to provide nailing surfaces to which the lading may be anchored. This lining 18 is nota part of myl invention except a combination claim I make for means of securing the lining to the end wall which is peculiar to my particular endwall. A Experience has shown that the lower por,- tion of car end walls are subjected? to greater and more frequent end thrust thanany other part thereof, therefore, it is essential that the lower part adjacent the floor be stronger than any other part.

yTo obtain this desired result I make the' lower plate 19 narrower than the upper plate 20 but each plate may have the same number of panels'within panels, as shown in Fig. 9. It is obvious that the lower plate 19.is then stronger per linear vertical inch than the upper plate. l A j The desired result described inthe last paragraph may be obtainedfas shown in V Fig". 1Q, wherein the lo'wer plate 21 is narrowerthan the upper vplate 22 but the margins 23'between the panels are allthe same width, thus requiring a greater number of lpanels within panels in the upper sheet than in the lower sheet. These panels in the upy.per sheetv 22 may be shallower .than the pan- :els in the lower sheet 21.

i Another method of obtaining aJ sheet .metal wall structure'which is stronger adjacent the floor than'near its top is to posi- 7tion the panels within the panels nea-r the the plate, as shown in Figs. 1 1
